-the introduction of viral genes through lysogenic infections
-genes being passed from parents to offspring
Explanation:
Interphase: Add mushrooms to represent organelles and a ring of pepperoni to make a nuclear membrane. Strips of peppers would represent the DNA inside the nucleus. To model the end of interphase, double the number of mushrooms on the pizza to indicate the copying of the organelles. Double the number of peppers inside the nucleus to represent the replication of DNA.
Prophase: Pair strips of pepper inside the nucleus to show the formation of chromosome pairs. Strips of aluminum foil would represent spindle fibers.
Metaphase: Line up the pair of peppers along the middle of the pizza. Removing the pepperoni would show the breakdown of the nuclear membrane.
Anaphase: Split up the pairs of peppers, and show the spindle fibers, made of aluminum foil, pulling them to either side of the cell.
Telophase: Make two new nuclear membranes around the pepper strips using pepperoni. Separate the pairs of peppers to show the chromosomes unwinding.
Cytokinesis: Cut the pizza across the middle to show the cell dividing into two daughter cells.
global warming is a increase in earths overall temperture caused increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.
to prevent global warming we could:
Drive less, Recycle more, Use less hot water, Plant a tree, Turn off electronic devices when not being used such as a T.V
all of these ideas save pounds of carbon dixoide and if you look above it is listed as a cause of global warming
